Now, the pill poison in Xu Yi's body had finally accumulated to the point where he could no longer continue cultivating.
Even if he had a water-type cultivation technique to continuously cleanse his meridians, it would be useless.
After all, in the past ten years, Xu Yi had taken about ten high-grade Chi-amassing Pills every day. It was already quite amazing that he could persist until now.
Feeling waves of power pushing him away, Xu Yi made the decision to return. Moreover, this time, it was finally not the soul that returned.
"Pa."
His body disappeared from the world, and the mark he left in this small world was completely erased.
He slowly opened his eyes and saw the wonderful bubble space again.
Xu Yi immediately felt the surging spiritual energy in his body stir.
After more than ten years of accumulation, his spiritual power had long reached the peak of the fourth level of Qi Refining. However, due to the countless pill poisons in his meridians, the flow of spiritual power was not smooth, and he was unable to advance further.
However, after he returned to the Federation, the pill poison in his body was completely gone. Once the ten years of bitter cultivation returned to his body, he immediately triggered the opportunity to advance his level.
Xu Yi sat down without hesitation and said,""Activate the Spirit Gathering Array for the Qi Refinement realm."
In the next moment, the bubble space was filled with dense spiritual energy of heaven and earth.
Xu Yi did not continue to take the pill because the spiritual power accumulated in his body was more than enough. Coupled with the spiritual power from the outside world, it was not a problem for him to pass the fourth level of Qi Refinement.
As expected, when the spiritual energy gathered and formed a turbulent force, it crushed down all the way. Any pass was instantly destroyed.
The ling power in his body circulated once and gradually underwent a subtle change.
Metal produces water, and water produces wood.
When Xu Yi advanced to the fifth level of Qi Refinement, the True Qi he circulated began to possess the characteristics of wood-type cultivation techniques.
Of course, this didn't mean that Xu Yi couldn't use metal-type or water-type cultivation techniques.
As long as he was willing, he could switch between these three cultivation techniques. However, at the same time, only one type of spiritual energy could be retained in his meridians.
However, when he continued to accumulate it, it had to be wood attribute spiritual energy.
When the wood attribute spiritual energy flowed in his meridians, Xu Yi had a clearer feeling that his meridians had become more and more tenacious and powerful.
If the water-type cultivation technique was a cultivation technique that could cleanse the meridians and remove the pill poison sludge, then the wood-type cultivation technique was a cultivation technique that could nourish life and increase one's foundation.
The combination of water and wood could make a xiuzhe's body stronger.
After silently feeling it for a moment, Xu Yi heaved a sigh of relief and said,"Cancel the Spirit Gathering Array."
"The spirit gathering array has been canceled. You have spent 15,000 yuan. Thank you for your patronage.”
In the room, a cold mechanical voice rang out.
The corner of Xu Yi's mouth twitched slightly. He had long known that there was a fee for using resources in the bubble space.
However, he was still a little surprised that the cost was so expensive.
This fee was about twice as expensive as the school.
Fortunately, there was still enough money in the card that Li Yi had transferred to him.
When he swiped the card, Xu Yi was slightly emotional. The system could increase everything by a hundredfold, except for the Federation's money.
Perhaps, this was because the Federation was too powerful. Most of the money transactions were monitored, so even the system was unwilling to touch it.
After swiping the card, Xu Yi successfully left the bubble space.
After returning home, he met his parents and had a warm dinner.
Going to the Heavenly Reincarnation Tower every day would cause a very bad thing. That was, the time spent in the Federation was too short, and the time spent in the foreign world was too long.
If it was an ordinary student, they would only stay for seven days every three days. It should not have much of an impact.
However, if it was Xu Yi, he would only be in the Federation for a day, but he would be in the Otherworld for more than 700 days.
This would cause him to be confused and unable to recognize himself. Over time, he might even treat the Otherworld as his home ground.
At this moment, he needed powerful cultivation and mental power to suppress it.
The higher one's cultivation, the more one could persist in one's self and recognize one's true self.
Fortunately, Xu Yi had the wisdom to distinguish between reality and play. He would not encounter any problems in the short term.
The next day, when Xu Yi arrived at school, Li Yi immediately called him over.
Looking at Xu Yi, Li Yi suddenly frowned and said,""Xu Yi, what kind of Breath Holding Skill are you practicing?”
"Teacher Li, what's wrong?" Xu Yi was startled.”
According to the Federation's regulations, the cultivation technique that a person cultivated was a very secretive matter. Even if the teacher asked, they had the right to not say it.
Li Yi shook her head and a hint of helplessness flashed in her eyes.""Your Breath Holding Skill is very powerful. Even I can't see through you completely.”
Those who were able to become high school teachers in the Federation were at least Golden Core cultivators.
However, an Aurous Core Stage cultivator was actually unable to see through the exact realm of a Qi Cultivating Stage cultivator. How shocking was this?
